Using a good quality air filter can address a number of indoor air quality problems in the home—from too much dust to pollen, pet dander, and dust mites. Sometimes, however, certain types of indoor air pollution can be harder to clean up. UV lights, or ultraviolet germicidal irradiation (UVGI), may be the solution you’re looking for.
What’s in Your Indoor Air?
Your indoor air can be full of harmful particles, including mold, mildew, fungus, and bacteria. You can trap some of these particles if you have a good quality air filter, but other particulates may elude capture and remain in your HVAC system.
As your air conditioner dehumidifies your home, too much condensation can collect inside the unit. When conditions are too moist, buildup of mold, mildew, algae, or bacteria may take up residence in the HVAC system. As these organisms thrive, the air handler may be re-circulating them into the home’s air. Mold and the other potentially harmful substances may aggravate respiratory problems such as asthma, emphysema, chronic bronchial irritation, and allergies.
How UV Lights Work
Ultraviolet light changes the DNA of cells and prevents them from replicating. UV lights are installed near the A/C’s evaporator coil and in the ductwork, where they target mold, fungi, algae, mildew, and bacteria that may be living on the surfaces. The UV bulbs are on continuously, and even though they last a long time, they may need to be changed every couple of years as their effectiveness decreases over time.
Ultraviolet lights also help kill algae that may collect on the surface of the evaporator coil, which can cause the air conditioner to cool less effectively.
